The main report describes the characteristics and operation of the relief well systems at Wolf River and Nonconnah Creek projects, Memphis, Tennessee, and summarizes the principal design features of the well system. Various factors influencing the design and operation of the wells are discussed. Appendix A contains an analysis of the performance of the well systems during high water in 1943, 1944, 1945, and 1947. An analysis of the high-water period in January and February 1950 is presented in Appendix B. An analysis of field pumping tests conducted in 1948, 1949, and 1950 is contained in Appendix C. Appendix D is an analysis of field pumping tests performed in 1951 to determine the efficiency of the wells and effectiveness of various cleaning agents for restoring the capacity of the wells to their former value.
